Title:	柴油垃圾車加裝濾煙器對排氣濾煙效果之研究 The Removal Efficiency of Exhaust Gas Emitted from Diesel Rubbish Trucks by Retrofitting a Diesel Particulate Filters

Keywords:	In this study, the active regenerative Diesel particulate filter (DPF) was installed on 50 diesel garbage trucks to discuss the effect of DPF on the reduction of air pollutants emitted by diesel vehicles. Observed from 2015 to 2018, the opacity of the test vehicle before and after the installation of the filter was measured, and based on the opacity rate, 10 measurements were taken after the regular time after the installation of the DPF. Understand the situation after using the filter for a long time and reusing it. The research results show that before the installation of the DPF, there are 28 exhaust emission opacity of more than 1.2 in 50 diesel vehicles, the failure rate is 72%, and the opacity is effectively reduced after installing the DPF. The total number of effective detections of 50 times, the total number of opacity is 0, up to 49 times, the ratio of opacity to 0 is as high as 98.3%, and the opacity is not 0, only 1 time. The ratio of opacity to non-zero is only 1.7%, and only one of the vehicles in the ninth test has an opacity exceeding the emission standard of opacity of 0.6. The cause is the filter. Damaged or not developed due to regular maintenance, and other vehicles did not have this problem, indicating that DPF installation and long-term regeneration use has the effect of reducing particulate pollutants. 柴油車不透光率柴油濾煙器 Diesel car Opcity Diesel Particulate

Abstract:	本研究將主動再生式柴油濾煙器(Diesel particulate filter, DPF)分別裝設於50輛柴油垃圾車上，探討DPF對柴油車排放空氣污染物減量之影響。觀測自2015年至2018年對測試車輛於裝設濾煙器前後之不透光率進行量測，並以不透光率為依據，在加裝DPF後定期時間後進行10次量測，以瞭解長時間使用濾煙器並再生使用後之情況。研究結果顯示，裝設DPF前，50輛柴油車有28輛排氣不透光度超過1.2的排放標準，不合格率達72%，在裝設DPF後有效降低不透光率，在所有車輛的50輛次的總有效檢測次數，不透光率為0的總次數高達49輛次，不透光率為0所佔比例高達98.3%，不透光率不為0僅為1輛次，不透光率不為0所佔比例僅有1.7%，而其中僅有1台車輛在第九次檢測的不透光率超過不透光率為0.6的排放標準，導因乃是濾煙器有破損或未養成定期保養而造成，而其他車輛未有此問題，顯示DPF的安裝及長期再生使用具有粒狀污染物減量效果。
